Description and Introduction

Zener TVSs The SMCJ48CA is a bidirectional TVS (Transient Voltage Suppressor) diode manufactured by **CONCORD**.  

### **Specifications:**  
- **Voltage Rating (V₃₀):** 48V  
- **Breakdown Voltage (VBR):** 53.3V (min) to 58.9V (max)  
- **Peak Pulse Power (Pppm):** 1500W (10/1000μs waveform)  
- **Standoff Voltage (VWM):** 48V  
- **Clamping Voltage (Vc):** 77.4V (at 10A)  
- **Leakage Current (IR):** 1μA (max) at VWM  
- **Junction Capacitance (Cj):** 500pF (typical)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Descriptions and Features:**  
- Designed for **ESD and surge protection** in electronic circuits.  
- **Bidirectional** polarity for protection against positive and negative transients.  
- **Low clamping voltage** for effective transient suppression.  
- **Fast response time** (typically <1ns).  
- **RoHS compliant** and lead-free.  
- Suitable for **telecommunications, automotive, and industrial applications**.

Application Scenarios & Design Considerations

Zener TVSs

Alternative Part Number

  • 1.5SMC48CA --: Same 1500W bidirectional TVS class with 48V standoff voltage, widely available and electrically equivalent for transient suppression.
  • P6SMB48CA --: 600W bidirectional TVS with matching 48V standoff; lower power rating but suitable for many clamp applications where SMCJ48CA is over-specified.
  • SMAJ48CA --: 400W bidirectional TVS with same 48V standoff voltage, compact SMA package, good drop-in for space-constrained designs with lower surge requirements.
